KINGSPORT — Amateur radio operators from throughout the Southeast will be coming to the Tri-Cities next month for a special event called Summits on the Air. Organizer Patrick Harris said the event will allow these radio operators — or “hams,” as they are sometimes called — to meet other hobbyists and engage in a bit of friendly competition. “Summits on the Air is an awards program (think trophies and certificates) where we hike to mountaintops, set up small portable radios and antennas and try to make radio contacts,” Harris said.
